Description

The present invention relates to a road safety facility for use in illuminated signs, indicator lights, and the like.

In the reflection sheet and the light emitting diode (LED) indicator lamp currently used for nighttime, a light source for illumination and a power supply facility associated therewith are required. Display panels using reflectors and retroreflection are relatively inexpensive, but cannot emit light continuously. For these reasons, the installation location on the road is easily restricted. There is a possibility that the situation of the visual recognition by the reflected light from the headlight of the vehicle may be delayed, leading to an accident.

As described above, the light source for illumination is required for the reflective sheet and the light emitting diode (LED) indicator lamp currently used. Display panels using reflectors and retroreflection are relatively inexpensive, but they cannot emit light continuously.
The present invention solves the above-mentioned problems in Pattellite, makes it difficult for installation to be restricted because it does not require power distribution equipment, and Pattellite incorporating the improvement of visibility by continuous light emission using a phosphorescent material as a road safety facility. It is to provide.

In order to solve the above problems, the present invention uses a phosphorescent material as a light source in place of a conventional reflector, retroreflection, or fluorescent lamp or LED. The phosphorescent material to be used is an afterglow pigment with ultra-high brightness and long afterglow, and when it is irradiated with non-ultraviolet light such as sunlight, fluorescent light, or electric light, it activates itself to emit light. As shown in FIG. 1, the phosphorescent tube 3 contains a phosphorescent material or is applied to the surface.

As shown in FIG. 1, the tube-shaped luminous body 3 is inserted into a transparent pipe such as a transparent resin pipe 1 to excite the light emitted from the phosphorescent material. Arrange so that.
(Claim 1)

Further, a reflection sheet 2 with improved light guide properties is wound between the transparent resin pipe 1 and the light storage tube 3 so as to take in external light and illuminate the light storage tube 3 with diffused light by light guide.
(Claim 2)

In the Paterlite according to claim 1 or 2, one or a plurality of LEDs 4 are arranged on the end face or both ends of the transparent resin pipe 1 as shown in FIG.
(Claim 3)

In the Paterlite according to claims 1 to 3, the reflection sheet 2 is wound around the transparent resin pipe 1 and the phosphorescent tube 3 as shown in FIG. 3. At that time, means for guiding the incident light in the circumferential direction by setting the outer peripheral side cross-sectional shape of the reflection sheet 2 to a triangular shape, an uneven shape, a saw shape, and an arc shape. Alternatively, the cross-sectional shape of the inner wall of the transparent resin pipe 1 is triangular, concavo-convex, sawtooth, or arcuate, and the reflective sheet 2 and the phosphorescent tube 3 are arranged on the inner side to guide incident light in the circumferential direction. means.
(Claim 4)

In the Pattellite according to any one of Claims 1 to 4, external incident light is refracted and transmitted once when irradiated to the transparent PVC resin pipe 1 as shown in FIG. 4 to generate reflected light and transmitted light in the reflective sheet 2. . Incident light repeatedly reflects and transmits for a while, then diffuses and travels on the circumference, and excites the phosphorescent material contained in the phosphorescent tube 3 or coated on the surface.
(Claim 5)

When the Pattellite of the present invention is used, for example, the power source can be self-supplied by the solar cell mounted on the top and the control city, so there is no need to install a power source and no electricity charges are generated.

The pattellite of the present invention incorporates a phosphorescent tube 3 inside a transparent resin pipe 1 and, by taking in external light, causes road safety light to be emitted in the tunnel at night for about 10 hours or more.

In order to enhance the light-emitting effect of the phosphorescent tube 3, the Pattellite of the present invention is disposed by winding the reflective sheet 2 between the transparent resin pipe 1. The surface of the reflection sheet 2 or the inner wall of the transparent resin pipe 1 is processed so as to have a cross-section such as irregularities, triangles, arcs, etc. to improve the light guide and diffusibility of external light, and the luminous effect of the phosphorescent tube 3 To increase.

The Pattellite of the present invention is provided with one or a plurality of LEDs 4 or the like disposed above or below the phosphorescent tube 3 in order to maintain a light emission effect at a constant amount, and irradiated with non-ultraviolet light intermittently lit by a control unit. The phosphorescent material contained in the tube 3 or applied to the surface is excited. Thereby, the Pattellite can maintain the light emission state. The aforementioned LED lamp is a self-powered system that receives power supply from a solar cell and a control unit disposed on the upper part of the main body.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 5 shows an external view of the Pattellite. The upper solar cell 5 and the control unit 6 supply power to the LED 4. In FIG. 1, a phosphorescent tube 3, which is a luminous body containing a phosphorescent material or coated on the surface, and a reflection sheet 2 are disposed between the pipes 1 made of transparent resin. As shown in FIG. 2, one or a plurality of LEDs 4 are arranged at the upper or lower portion of the light storage tube 3, and non-ultraviolet light is intermittently emitted from the controlled LED lamp to be contained in the light storage tube 3 or applied to the surface thereof. Is excited by irradiation to maintain its emission. In FIG. 3, the reflection sheet 2 is wound around the transparent resin pipe 1 and the phosphorescent tube 3 in order to enhance the light emitting effect. The surface of the reflection sheet 2 or the inner wall of the transparent resin pipe 1 is subjected to a surface having a cross-section such as irregularities, triangles, arcs or the like, or internal processing, and external incident light is applied to the transparent resin pipe 1 as shown in FIG. When irradiated, the light is once refracted and transmitted to reach the light storage tube 3 to generate reflected light and transmitted light. Incident light is repeatedly reflected and transmitted for a while, then travels on the circumference, diffuses, and irradiates the phosphorescent material of the phosphorescent tube 3 to excite it.

  The Pattellite of the present invention is limited in installation because it does not require power distribution equipment compared to currently used reflector sheets, light emitting diode (LED) indicator lamps, or reflectors and retroreflective display panels. It is to provide Pattellite as a road safety facility that incorporates difficulties, visibility improvement by continuous light emission by using phosphorescent material, etc. Furthermore, since it is also energy saving, it can be expected to contribute to society.
